Invasion experiment data

Data collected from experimental laboratory invasions of the bean beetle Callosobruchus maculatus. Data show the post-dispersal densities of beetles in each patch of the one-dimensional invasion array. Columns (in order) are date, start time, end time, population ID, generation (1-10), treatment (0 = spatially sorted, 1 = shuffled), array_patch (the patch number in the dispersal array), array_shift (the cumulative number of patches that the invasion has been shifted towards 0 each generation to ensure that the invasion would fit in the spatial extent of the array), invasion_patch (array_patch + array_shift), N_females (number of females in each patch), N_males (number of males in each patch), N_unsexed (number of unsexed beetles in each patch), and notes.
